Super Sciency Guy Stands Cli-Sci On It’s Ear

In a story, not unrelated to my previous post……..

Wikipedia describes Greenhouse Gases in this manner…….

A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In the Solar System, the atmospheres of Venus, Mars, and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth’s surface would be on average about 33 °C (59 °F) colder than at present.

Since the beginning of the Industrial Revolution, the burning of fossil fuels has contributed to the increase in carbon dioxide in the atmosphere from 280 ppm to 390 ppm, despite the uptake of a large portion of the emissions through various natural “sinks” involved in the carbon cycle. Anthropogenic carbon dioxide (CO2 ) emissions (i.e., emissions produced by human activities) come from combustion of carbonaceous fuels, principally wood, coal, oil, and natural gas.

This is from Why the Global Warming Skeptics Are Wrong by William D. Nordhaus.  He’s a carbonphobe of the economist vein. 


The heavy black line is the actual temperature record, while the heavy blue line is the models’ average calculated global temperature with only natural forcings (“Without GHG s”). The several thin blue lines are the results of the individual models, while the gray vertical lines represent major cooling events due to volcanic eruptions.

The top part shows the calculations with both natural forces and with estimated greenhouse gas concentrations and forcings. Again, the heavy black line is the actual temperature record, while the heavy red line is the models’ average calculated global temperature with CO 2 and other greenhouse gases as well as natural forces (“With GHG s”). The cloud of thin yellow lines represents the results of the individual models
This experiment shows that the climate models are consistent with temperature trends over recent years only if the estimated warming induced by accumulations of CO 2 and other greenhouse gases are included. The source is Climate Change 2007: The Physical Science Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change edited by S. Solomon and others (Cambridge University Press, 2007), p. 685f

Lol, how’s that again?  (Presumably, Nordhaus isn’t removing H2O from the models. But, it isn’t clear in the representation.)  In the first half of the last century, CO2 had no effect on the global temps?  So, the first 40ppm above the magical 280 ppm didn’t do squat, but the next 40ppm caused a 1/2 degree increase in the global temps.  Well crap, now we’re going to have to throw all of those silly science texts out about the doubling and logarithmic effect of CO2 and other GHGs.  Do overs!!! 

Morons.  I hate the dumbing down of society.

  1. Haha, without GHGs the simulations make it warmer until 1935 (or so). I wonder if anybody thought that was a problem.

  2. Mike Davis says:

    BUT,BUT,BUT, it is the model estimated climate compared to the model estimated actual.
    What they call actual is ACTUALLY a model estimate, not the actual temperature because the technology is not even today advanced enough to give us an actual global average surface temperature. We have lots of versions of “Best Guess” surface temperatures.
    He lost his argument on that minor issue alone.
